Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for fusing the cloth-like surfaces of a composite material of a thermoplastic synthetic resin such as soft vinyl chloride and a cloth-like material.

For the purpose of imparting airtightness, thermoplastic synthetic resins such as soft vinyl chloride are laminated or coated on the back side of cloth-like materials, but composites of such cloth-like materials and synthetic resins The materials are conventionally joined by stitching.

In the case of sutures, the disadvantage is that the seams form holes and the airtightness is broken.

Particularly in the Ru7 lining of automobiles, it is common practice to laminate a vinyl chloride sheet on the back side of the fabric to eliminate air permeability. Similarly, with sutures, ventilation occurs through the needle holes, and air contaminated with cigarette smoke in the car interior passes through, making the seams especially dirty, making the beautiful interior look f'? There will be no.

Therefore, various researches were conducted in an attempt to somehow achieve a seamless connection, and as a result, the present invention was developed.

That is, thermoplastic synthetic resins such as vinyl chloride (1)
A material obtained by bonding to a cloth-like material (2) by laminating, etc.
The cloth-like surfaces are brought together and a thermoplastic synthetic resin inclusion (3) such as vinyl chloride is sandwiched therebetween and fused by high frequency or the like.

In the figure, (4) indicates a fusion bar, and (5) indicates a fusion receiving plate.

In the example shown in Fig. 1, a thermoplastic synthetic material (1) consisting of a vinyl chloride sheet is laminated on the back side of a cloth-like material (2). This is a diagram of folding and high-frequency wells, which is used to pass automotive roof lining adhesive wire.
It is an attempt to obtain.

When bathed in this way, the thermoplastic synthetic resin inclusion (3) made of the vinyl chloride sheet sandwiched in between and the thermoplastic synthetic resin (IJ) that was folded in half and thus formed the top and bottom surfaces fuse together. The cloth-like material (2) is fused through the gap and a seamless joint is achieved.

When the joint is expanded in this way, as shown in Fig. 2, a wound part (B) is formed following the fusion part (A), and a wound part (B) is formed following the fusion part (A). If (B) is made into a wire pocket through which a listing wire is passed, it is possible to obtain a Roux 7 lining that does not get dirty since there is no needle hole in the seam.

In addition, in the case of simply joining together for general use, as shown in Figure 3, the two composite materials to be joined are placed with thermoplastic synthetic It is sufficient to sandwich the resin inclusion (3) and perform high-frequency welding, and when the fused product is developed, a seamless seam can be created as shown in Fig. 4.

The best fusion state can be obtained if the thermoplastic synthetic resin inclusions (3) are of the same quality as the thermoplastic synthetic resin (1) composited with the cloth-like material (2), but even if they are of different types, There are many things that can be joined.

As described above, this invention seamlessly forms a composite of a cloth-like material and a thermoplastic synthetic resin by simply interposing a thermoplastic synthetic resin between the superimposed composites. Since it can be fused, it can be joined without impairing the airtightness, which is the main purpose of such composites.

Claims (1)

[Claims] A composite material such as a thermoplastic synthetic resin such as vinyl chloride, which is laminated onto a cloth-like material, is placed face-to-face with the cloth-like material, and a thermoplastic synthetic resin such as vinyl chloride is sandwiched between the resin inclusions and subjected to high frequency, etc. A method for fusing cloth-like surfaces of a composite material of a synthetic resin and a cloth-like material, characterized by fusing together surfaces of a cloth-like material.
